'lElDWAR-JD W. BURGESS, OF CHICAGO, ILLINOIS, ASSIGNOR,

INTERNATIDNAL. HARVESTER COMPANY,

To aZZ whom it may concern:

Be it known that l, EDWARD W. B RcEss, a citizen of the United States,residing at Chicago, in the county of Cook and State of lllinois, haveinvented certain new and useful Improvements in Tractor-peratedHay-Treating Devices, of whieh the following is a full, clear, and exactspecification.

y invention relates to tractor operated hay treating devices, such,forexample, as hay rakes.

The object of this invention is to accomplish the efieient propulsionand operation y and from a tractor.

Another object is to provide a construction of rake frame and operativeparts that may be connected with a tractor in offset and trailingrelation and have its taking elements driven by means of operativeconnections with the power transmission gearing of the tractor andeliminating the tractive power elements from the rake structure;

v l have illustrated one embodiment of my invention in the accom panyingdrawings and in these drawings,-

he power transmission gearing for transmitting the power from the engineshaft to the counter shaft which operates the rake shaft is illustratedin detail in Fig. 2 and will now be described.

The same transmission to transmit the power to the traction wheels ofthe tractor and this description therefore will also include the drivingmechanism for the traction; Wheels.

, Power is transmitted from the engine shaft to the traction wheels bymeans includ- 111g ap1n1on48 secured to the engine shaft 4t and meshingwith an orbital gear 49 journaled on the stud-50 secured to one arm 51'of a three-armed spider, the arms of which radiate from ahub 52 wherebyit is secured to one end of a sleeve 53 that is journaled upon-the crankshaft 4 at one end of the pinion 48. A driving sprocket 54 is formedintegral with the body of the sleeve 53 and power is transmitted to thetraction wheels by means of a chain 5 which connects the drivingsprocket 54: with a corresponding sprocket carried by the main axle ofthe tractor. with a hub 56 journaled upon the shaft d at the oppositeend of the pinion 48. A series of studs 57, preferably three in number,is secured tothe carrier and each stud has journaled upon the same arotatable gear 58 which meshes with the pinion 4-8. A wheel 59 isprovided with a hub 60 which is secured by means of a key 61 to hub '56.

riphery with .a two-partcasing 63 is providedwith a hub 65- which isjournaled upon the hub 52 and also'provided with a rim 66 having aninternal gear ring 6'? which meshes with the gear'dQ. This member lid isalso provided with a peripheral flange 68 which is secured by means ofbolts 69 to the member 70 which forms the other portion of the two-partcasing and has a corresponding peripheral flange '7' 1, the flanges 6band '21 being bolted together. The member 70 is also provided with aIhub'72 which is journaled upon the hubttl of the wheel 59. A'gear' ringV3 is carried by the arms 51 and meshes with the Specification.ofLetters Patent.

The driving connections for'the counter shaft will now be described.

The counter shaft as above. set forth is 3' ournaled on the tractorframe and is disposed parallel with the engine shaft and is located in aplane nelow the engine shaft, as clearly shown in Fig. 3. The means fortransmitting motion to the count'ershaft is operative whether thetractor is moving or is stationary, and includes a gear 78 secured tothe inner end of the sprocket sleeve 53, a collar 79 beingmounted' onthe-sleeve between the gear and the engine frame. A gear 80 is securedto the hub 65 of the casing 64. The gear 78 meshes with an intermediatepinion 86 journaled upon a bracket member=87 secured to the tractorframe and the intermediate union 86 meshes with a gear wheel 7j-ournaled upon the countershaft. The gear "80 meshes with a gear wheel8 also journaled rod- 11 extending rearward within convenient reach ofthe operator. In operation, with the engine running idle,

the crank shaft transmits motion through the-pinion48 to the orbitalgear Wheels 49 and 58, then to the casing 63 through the orbital gears49 and the gear ring 6 through the gear ring 58 to the carrier 55andwheel 59. When the casing i's-held against rotation by means of theorbital gear wheels 49 engaging with the gearring 67 and the frictionband mechanism and arms 51, will be carried around the axis of theengine crank shaft thereby rotating the sleeve 53 in a forward directionand the gearwheels 7 on the countershaft 6 through the intermediatepinion 86 and the gear wheel 78 in the same directionand the tractormoves forward driven by the sprocket chain. If the friction bandmechanism is caused to hold the wheel 59 against rotation the orbitalgear wheels 58 will turn the gear ring 73 about the axis of the engineshaft, thereby rotating the gear supporting arms 5l'and the sleeve 53 ina direction to reverse the movement of the traction wheels. Whenthetractor is held stationary by 'means of the brake mechanism thesprocket wheel 54 holds the sleeve 53 and the arms 51 against tor, as bymeans of '27 represents a diagonally disposed brace 73 and gear wheelsrotation and the orbital gear 49 through the gear ring "67 will impartrotative movement to the casing 63 about the axis of the crank shaft andthe gear 80 rotates the gear wheel 8 while the tractor is heldstationary and the 'countershaft becomes available for transmit-- tingthe power to the hay rake which is also stationary,

The hay treating device or rake includes a rectangular frame disposed atone side of the tractor and inclined forward and out-tward relative tothe line of draft, and including front and rear frame members 13 and 14,respectively, and front and rear end members 15 and 16, respectively.The front of the frame is supported by meansof a trailing caster wheel17 connected with the frame. member 14 by means of a bracket casterWheel 19 connected with a bracket member 20 secured to the rear cornerof the frame. a 21 represents a transversely .disposed draft memberhaving one end secured to the end member 15 and to the, front end of theframe member 13, and its opposite end detachably connected with thetruck frame of the tractor, as by means of a conpling pin 22, and 23represents a supplemental draft frame member having its rear end securedto the middle-part of the frame members 13 and 14 and its front end tothe draft member 21 near its connection with the tractor. 24 representsa-draft member havmg its rear end secured to the end frame member-16,and-its front end detachably connected with the draft frame 25"of thetraca coupling pin 26, and

member havingits rear end secured to the frame member 13 and its frontend to the front end of the draft member 24.

The raking elements have a common form,

member 18, and its .rear'end by at similar and include a raking cylinder28 having an 4 axial shaft 29 journaled in bearings secured to the endmembers of the rake frame and having spider arms 30 secured thereto, andcarrying rake tooth carrying bars 31 at their .free ends that areprovided with crank arms 32 at their front ends that are operativelyconnected with a controlling spider 33 journaled upon the rake carryingframe eccentric to the axis of the shaft 29 in a common way.

-Means.fort ransmitting motion to the raking cylinder include a gear 34secured to the front end of the shaft 29 and meshing with a pinion 35secured to one end of a transversely disposed shaft 36 journaled in abearing 37 carried by the rake frame and having a coupling member 38secured to its opposite end whereby it is preferably flexibly connectedwith one end of a transversely disposed shaft 39, having its oppositeend -connected, by means of a spline, with a coupling sleeve 40 securedto the extended end of the supplemental countershaft'fi of the powertransmission gearing of the windrow is delivered in rear of the tractortractor.

In operation, the raking elements are driven independently from thegearing upon the tractor and controlled by the operator by means of theclutch mechanism. The

and'arrangement of its parts without departing from the spirit of theinvention as indicated in the appended claims. What I claim as myinvention, and desire to secure by Letters Patent, is:
